I did try using the 0.2.8 release after the 0.2.7 release and the current snapshot (dated 170703 I think) with no difference between the 3. It appeared that sometimes I'd get sound and sometimes I wouldn't. However, everynow and again, it will get to a point where where I can't get any sound at all and can only get it working when I remove and reload the modules. > > The only thing I can think of is that recently emerge upgraded my > version of gcc from 3.2.2 to 3.2.3-r1 and glibc from 2.3.1-r4 to > 2.3.2-r1.

I found that when the sound wouldn't work in recording (either via /dev/dspx OR the direct output), it quite often would work via the direct output when I dropped back to the menu suggesting some sort of mute toggle not always toggling properly. I do however usually get sound after a number of retries. > > This is not a sound output issue as previous recordings play > back fine. Ditto I'm currently trying to get a SAA7134 programming manual through some contacts of mine (I'm an electrical engineer). If I could just get this little prob sorted I'd be so happy. CH
